Heard about a friend who's got mono? Here are some quick facts about mononucleosis.
- It's an infection caused by a virus (the Epstein-Barr virus or EBV).
- Mono is very common in teens.
- Mononucleosis is contagious! If you've got mono, you can spread it to others.
How Do I Know if I've Got Mono?
Sometimes you can have mono and not even know it. Young kids usually have pretty mild symptoms. But teens can have more severe symptoms.
Symptoms of mono include:
- Feeling really tired and weak
- Not feeling hungry
- Puffy eyelids
- Sore throat
- Swollen glands in your neck
- Swollen spleen under the left side of your ribs
Symptoms usually occur about four to six weeks after you come in contact with the virus.
What Happens When I Visit the Doctor?
Your doctor will examine you and check your neck for lumps or bumps. You will be asked questions about your symptoms. Make sure to tell the doctor about all your symptoms.
Your doctor may do some blood tests, including:
How Is Mono Treated?
There is no cure for mono. The virus eventually goes away, but it can take a few weeks.
Your doctor or nurse will recommend the following steps to make you feel better:
- Get plenty of rest. Sleep helps your body fight the infection.
- Avoid contact sports as well as other activities until your doctor says it's OK. This helps protect your spleen. A hit or fall could make it break open, or rupture. A ruptured spleen causes internal bleeding, which is a life-threatening condition.
- Drink a lot of fluids. If your body does not have enough water, you can become dehydrated. Dehydration can make you feel worse.
- Rinse your mouth or gargle with salt water. This can help soothe a sore throat. You can also try sucking on hard candy or eating a Popsicle.
- Take acetaminophen (Tylenol) or ibuprofen (Advil, Motrin) for aches and pains. Do NOT take aspirin because of the risk of Reye syndrome, a rare but serious condition that typically affects people ages 4 to 14 who are recovering from chickenpox or another viral illness.
When Will I Feel Better?
Most of the time, mono symptoms get better within a few weeks. But be patient. It can take a little bit of time. Symptoms of mono can linger for weeks or even months.
If you don’t feel better in a few weeks, you'll need to go back to the doctor.
Even when you feel better, you will still need to avoid strenuous activity for about a month. Your spleen needs this time to heal.
Can Mono Cause Complications?
People rarely die from mono. But some complications of mono can be life threatening. One complication of mono is a ruptured spleen. Seek medical help right away if you have any of the following symptoms of a ruptured spleen:
- Sharp pain in the upper left side of your belly near the ribs
- Fainting or feeling light-headed
Other rare complications are:
- Brain infections such as encephalitis or meningitis
- Liver swelling
- Swelling of the testes in boys (orchitis)
If you have a weakened immune system, you are more likely to have severe mononucleosis. Certain diseases and medicines can weaken the immune system. This includes HIV/AIDS, chemotherapy for cancer treatment, and steroids.
Why Is Mono Called the Kissing Disease?
When you kiss someone, you are mixing your saliva with theirs. If you have mono and share saliva, you are sharing the virus, too. Kissing or having sex with someone with mono makes you more likely to get the infection.
How Else Can I Catch Mono?
Besides kissing, you may also catch mono if you:
- Are near someone with mono who coughs or sneezes
- Drink out of the same glass as someone with mono
- Share a fork, spoon, or straw with someone who has mono
A good tip to remember is NEVER share eating utensils, water bottles, or drinking glasses. Following this rule can help lower your risk of getting mono.
